AST SpaceMobile and Firefly Aerospace represent two distinct bets on the future of commercial space, each burning cash while chasing very different revenue models.
AST SpaceMobile (ASTS) is constructing a first-of-its-kind space-based cellular network designed to connect directly to standard mobile phones without specialized equipment.
Firefly Aerospace (FLY) focuses on launch services, lunar missions, and in-space operations primarily targeting government and commercial national security clients.
Both companies are burning cash at scale, but their paths to profitability, and investor risk, diverge sharply in ways that matter deeply to long-term shareholders.
AST SpaceMobile has assembled an unusually powerful roster of equity-holding clients, including AT&T, Verizon, Bell Canada, Rakuten, Vodafone, Alphabet, American Tower, and Telus.
By the end of 2026, the company expects to have 45 satellites operational, which would allow it to fully service the U.S. market and begin accelerating revenue meaningfully.
Wall Street projects ASTS will generate $149 million in sales for fiscal 2026, surging to $725 million the following year, when analysts expect the company to turn its first modest profit.
Positive free cash flow is not expected until 2029, meaning investors must remain patient through several more years of heavy spending and balance sheet pressure.
Firefly Aerospace carved out a historic milestone when it became the only private company to execute a successful lunar landing, touching down on the Moon in March 2025 with its Blue Ghost Mission I.
FLY only entered public markets in August 2025, pricing its initial public offering at $45 per share, giving it a relatively short track record for investors to evaluate.
Analysts project Firefly will surpass $440 million in revenue in 2026 and scale toward $1 billion in annual sales by fiscal 2028, driven largely by NASA and national security contracts.
Firefly Aerospace carries a lower price-to-sales ratio than AST SpaceMobile, which trades at a premium reflecting its disruptive direct-to-device potential rather than current earnings power.
Neither company currently carries a meaningful forward price-to-earnings ratio, underscoring the speculative nature of investing in either name at this stage of their development.
Firefly Aerospace’s position as a key supplier to NASA’s lunar ambitions, combined with its more conservative valuation, makes it the stronger pick for investors weighing risk against near-term revenue visibility.
